CITY OF CHARLOTTE
Third Parallel Runway
CHARLOTTE/DOUGLAS INTERNATIONAL AIRPORT
CHARLOTTE, NORTH CAROLINA
1.0 PURPOSE
The purpose of this storm water detention submittal is to obtain approval from the city of
Charlotte, to construct a new runway, parallel taxiway, two cross-connector taxiways,
and pre-grade for the relocation of Wallace Neel Road at the Charlotte/Douglas
International Airport (CDIA). This contract will include the clearing and grubbing, main
grading, pipe drainage systems, and perimeter channel construction. This Plan describes
the watershed, drainage, and detention systems for the disturbance of approximately 950
acres. The Plan has been prepared for the City of Charlotte (City) CDIA in general
accordance with the North Carolina Erosion and Sediment Control Planning and Design
Manual (Design Manual). Analysis
2.0 OVERVIEW OF WATERSHED
' The CDIA is proposing development of a new runway and taxiway system to the existing
aviation facilities. This third parallel runway and taxiway system is located on the
western portion of the airport property. The airport itself is located on the western side
' of Mecklenburg County. There are three large basins located around the airport. The
Paw Creek and Beaver Dam Creek basins drain to the Catawba River, while the Sugar
' Creek basin drains to Sugar Creek. All of the drainage from the runway will meet in one
of these three basins and flow to its designated river.
3.0 PROPOSED DEVELOPMENT PLAN
The runway area has a relatively level elevation creating the need for the site to be filled.
This will alter the drainage of the runoff in that instead of the runoff from this existing
property to travel across the ground and into a ditch, channel, or stream and off the
property, the runoff will travel off of the proposed pavement surfaces, across grassed
t

' shoulders and swales to drainage inlets, and through culverts and/or pipes prior to
discharging back into natural channels. The design of the drainage system has been
developed to incorporate surface water detention in several locations to reduce peak
discharge. In some instances, where runoff due to the site grading is diverted from one
' sub-basin to another, additional discharge control has been identified to maintain peak
discharge to pre-development conditions. An example would be system F discharging
' into system B. Some of the runoff from system F will drain to system B, then flow out of
system B and meet up with the rest of the runoff from system F, and eventually spill into
the Catawba River. This project will be built with two construction packages. The
' drainage system construction will require two phases. Package one will include all of the
clearing and grubbing, preliminary grading, and main drainage construction. Package
' two will include the remaining drainage, fine grading, pavement, and the lighting
construction. All proposed detention facilities will be installed in Package One, with the
exception the infield detention for System G. The remaining detention for System G will
' be installed as part of Package Two.
' 4.0 RESULTS OF DETENTION ANALYSIS
' A review of the existing drainage of the watershed basins that encompass this project, as
illustrated in Figure 2, and preliminary discussions with City of Charlotte Land
' Development staff provided us with the following philosophy for peak discharge control.
Runoff from several of the sub-watershed basins, as they leave the airport property,
converge with one another west of I-485 in a relatively short distance. Given this, each
' main basin was treated and evaluated individually with the multiple sub-basins leaving
the airport property being summed for peak discharge evaluation. Therefore, System L
' and M combine, while System G, H, and K combine, and System F and B combine to
form three separate discharge points of interest for the runoff to the west. System P brings
' runoff to the west and therefore will be included in with System H. System N drains
south to another basin.
' The detention in system F is located at F10, and the detention in system B is located at
B04. Some of the runoff from system F will spill into system B, and will combine in the
' detention at B04. The same idea is seen in systems G, H, P, and K, with detentions
located at G04-04, G16, G04-02, G04, G04-06, G10, and H10. Also Systems L and S
' combine with System M, with detentions located at M06 and M02.

72 q. t
The 100-year water surface elevations (WSE) for each inlet were calculated using
detention contained within the appropriate drainage basin. 100-year WSE established by
this method does not account for spilling from one basin to another.
The spill crest elevation between the inlet pairs (G04-04 & G04-02 and G04 & G04-06)
was estimated. When water surface elevation reaches the estimated crest elevation, the
water will spill from "less efficient inlet detention area" to more efficient one.
The resulting 100-year WSE for each pair is somewhere between the elevation of single
inlet.
For example: 100-year WSE for inlet pair G04 & G04-06 is between values 730.35 and
729.40. The elevation of 730.35 shall not be exceeded during 100-year storm event in
this inlet pair detention system.
